GAS-FEED REGULATOR AND KEY-RETAINER THEREFOR.

Application filed December 28, 1915.

To all whom it may concern:

Be it known that I, GoTTLmB F. BREUN- INGER, a citizen of the UnitedStates, and a resident of Bedford Hills, in the county of Westchesterand State of New York, have invented a new and Improved Gas-FeedRegulator and Key-Retainer Therefor, of which the following is a full,clear, and exact description.

Among the principal objects which the present invention has in view are:to provide means for predetermining the service position of a gascontrol feed key; to provide means for adjusting the service position ofthe key; and to provide means for holding the key in service to avoidloss thereof.

Drawings.-Figure 1 is a side view of an end fragment of a gas tank,showing in conjunction therewith, a delivery pipe and control valve, akey for said valve, and means for holding the key in position toregulate the feed of gas from said tank; Fig. 2 is an end view of thevalve and key therefor shown in Fig. 1, and the cap on which thesaid'valve is mounted; Fig. 3 is a detail view showing the resilientkeeper for the detachable handle with which the regulator is provided.

Descripti0n.As seen in the drawings, a gas tank 7 is closed by means ofa screw cap 8. The tank 7, as shown in the drawings, is of the charactergenerally employed on automobiles for transporting illuminating gasunder pressure. The cap 8 is conventionally provided with a valve 9 fromwhich is carried a delivery pipe 10.

The valve stem 11 employed in the present valve is provided with areduced wrench end 12 to receive a key 13 by which the said stem andvalve ports provided therein are manipulated.

To register the service position of the key 13, a bracket 14 is mountedon the barrel of the valve 9 and there secured by clamps 15, small bolts16 being passed through openings in the ends of the clamps andcorresponding openings in the bracket 14:. The bracket 14 has an endextension 17, which,

in service, is disposed in the path of the handle of the key 13.

i To hold the key 13 on the end 12 for the purpose of preventing theloss thereof, a retaining hook 18 is furnished to engage the key 13. Thehook 18 is held in engagement with the key 13, by means of a spiralspring 19, the end of which is anchored to a clamp p ollar 20 and to theclamping bolt 21 there- 0peratz'on.When a tank is provided with abracket 14: arranged as shown in the accompanying drawings, and as aboveset forth, the operation is as follows: The bolts 16 are loosened topermit movement of the bracket 14c and clamp 15 thereof around the valve9. The key 13 is moved to revolve the stem 11 to permit a rapid and fullflow of gas from the tank 7 to the delivery pipe 10 and lamps connectedtherewith. In prac tice, it is found that when lighting lamps suppliedfrom a gas tank, such as indicated in the accompanying drawings by thenumeral 7, a very free flow is initially required. The lamp having beenignited, the key 13, together with the bracket 14, are then manipulateduntil the flame in the lamps is disposed as desired in service. In thisposition of the key 18, the extension 17 is held firmly against thehandle of the key, while the bolts 16 are tightened to draw the clamps15 and the body of the bracket 14 firmly upon the valve 9, in whichposition the bracket and parts connected thereto will thereafter remain.Without testing the flow and the illumination dependent thereon, theoperator knows that the key 13 is in the position required to give thedesired flow of gas to the lamps.

If the operator desires the key 13 to re-. main in place, the hook 18 isslipped over the key, the spring 19 being expanded to permit thisaction. If, however, the operator desires to remove the key, the hook 18is released and is permitted to dangle from the spring 19. The operatorreleases the hook 18 and removes the key 13 only when he fears theannoyance of others using the key to disarrange the flow of gas.
